Los libros adquiridos son geniales, con contenido excelente y llenos de grandes conocimientos los cuales he empezado a poner en práctica en mis entrenamientos logrando un nuevo nivel en mi trabajo corporal...

I've only had a chance to overlook the material. I am in the 8 week transformation challenge workouts are great just got my food together, ran into the challenge 5 hours before start so this week has been a scramble organizing, planning, printing and prepping. Two thumbs up im looking forward to the next seven weeks.

Awesome programs

I think myself as an experienced trainer and could name 10 exercises per muscle group without having to think, but these ebooks have added a new dimension. There are some new exercises but overall it is the structure of the workout and the intensity I’ve been training at. I am four weeks in the shred and already my bulky frame is leaning out the shape is coming. At 102kg and 15% body fat, I am excited to see what happens for the next eight weeks.

Very interesting and informative, amazing pumps guaranteed

Loving them all so far cant wait to keep them up and and get some more

Fast and informative...kai is a great author...I look forward to his continued works...

So far into 3rd week of 12 week shred program and it’s phenomenal. I’m already seeing cuts and I feel great!

Kai is an amazing person and has taught me so much

It’s been good, I’ve started with push/pull going to do that for 4 weeks. Feel good already, a lot better time wise to train like this atm. Great price and awesome workouts on how to build/shred and how to count my macros properly

Not sure how it took me this long to find these books. 15 books for $15?! Unbelievably information and the workouts are killer. Chest of time workout had me dripping. Keep up the great work Kai. Look forward to more information

Knowledge is power!
